Traverse Matrix in Diagonal strips

Question

I thought this problem had a trivial solution, couple of for loops and some fancy counters, but apparently it is rather more complicated.

So my question is, how woul

Answer 1

I think this can be a solution for any type of matrix.

#include 

#define M 3
#define N 4

main(){
         int a[M][N] = {{1, 2, 3, 4}, 
                        {5, 6, 7, 8}, 
                        {9,10,11,12}};

         int i, j, t;
         for( t = 0; t=0 ; --i, ++j)
                     if( (i
